SPECIFICATION forming part of Letters Patent No. 244,986, dated August 2, 1881.

Application filed April 8, 1881. (No model.) Patented in France February 15, 1881.

To all whom it may concern Be it known that I, OGTAVE LrioN Dns- GHAMPS, of Paris, in the Republic of France, have invented a new or Improved Machine for Cutting the Gimp or Embroidery Threads in Tulles, Laces, Valeuciennes Embroidery, and Tarlatans, (for which I have obtained Letters Patent of France forfifteen years, dated February 15, 1881;) and I do hereby declare that the following is a full, clear, and exact description thereof, reference being made to the accompanying drawings.

In the manufacture of tulles, laces, valenciennes embroideries, tarlatans, and other similar fabrics by machinery, the mechanical production of' the designs necessitates the use of embroidery threads and gimps, which assist in the formation of flowers and other designs. The said embroidery threads and gimps have to be cut afterward, between each of the aforesaid flowers or other design, because they are useless and incumber the back of the'tissue.

' Heretofore the cutting of the embroidery threads or gimps has been done by hand, and this is a diflicult and costly process. By means of my new apparatus, hereinafter described and illustrated, this work is done mechanically.

My new machine is able to cut the gimp or embroidery threads in all kinds of tulles, laces,

&c., Whatever may be the shape of the designsor the nature of the tissue. ;It cuts better and more quickly than can be done by hand, and never pierces the tissue.

Figure 1 is-a vertical central section of the apparatus. Fig. 2is a sectional plan view; and Fig. 3 the plan of a modification. E In a wooden handle, a, is fixed a metallic tube, 1), which is cast or connected to three arms,

c c c, that terminate in a ring, 0. Through the tube b is passed a rod, d, which constitutes the shaft of the mechanism. At the upper end of this shaft is fixed a pulley, e, whose hub e rests on the tube 1). Around the hub e is swiveled a bar or disk, f, which carries two friction-rollers, f. These rollersare intended to guide the rope which gives motion to the pulley e, and to hold it close to the pulley a sufficiently for driving it.

To the lower end of the shaft 11 is joined, by'

a nut, d, a socket, g, which has three radiallyprojecting arms, 9 g 9, that carry the cuttingdisks h. These disks h are fixed on vertical pins 6 that hang in the arms 9, and that carry pinions 12, all gearinginto an annular rack, m.

This rack m is attached to the arms 0 c c of the ring 0, Within the ring 0 is secured an inner ring, at, having an inwardly-projecting horizontal cutting-flange l. The cutters h hear on this flange, and are held down on it by springs r that press upon the pins i.

To the outer side of the ring 0 is fastened an extension-arm, 8, whose edges, near its upper end, 8, are sharpened to out. On top of the arm 8 are two blades, t t, which cross each other, the upper blade, t, having its free end slightly curved upward to keep it from entering beneath the gimp or embroidery threads.

The lower faces of the arm 8, and of the cutting-flange I, must be strictly in the sameplane.

The machine operates as follows: By means of a convenient transmission a rope gives rotary motion to the pulley e, and consequently to the arms 9 which carry the cutting-disks h. The pinions p, 'meshing'into rack m, are thereby also rapidly revolved around their axes. The apparatus being firmly held in hand and caused to act, is moved in varying directions over the tulle or fabric whose gimp-threads are to be out. The operator watches attentively the end of the arm 8, and directs it underneath the embroidery or gimp threads. The arm 3 cuts these threads, either near their ends or, by the blade t t, in the middle. The ringc, being kept firmly on the fabric as it is fed along, raises the cut-threads and causes them to stand up, so that they are readily clipped 011' by the cutters h, acting on rin g-blade I. These threads are thereby clipped close to the fabric.

In. order not to miss clipping any threads which the blade 8 has cut open I may provide the lower side of the ring 0 with a ring or lining of felt, w, or any other frictional material, such as india-rubber. Such a felt ring can be held in place by an outer ring, as, as shown.

In Fig. 3 I show that the arm 8 can be projected into the ring I instead of projecting outward, as in Figs. 1 and 2. For the steel disks h, whose number is variable, I may substitute equivalent rotary knives.

The ring a may contain arms or inward projections, which assist in raising the gimp or embroidery threads and presenting them to the knives.

I claim- 1. The gimp cutting and clipping instrument consisting, essentially, of the rotating cutters h h carried on a revolving shaft, (1, the fixed annular blade I, handle a, and of the cuttingarm s, all combined to operate substantially 10 as herein shown and described.

2. The combination of the blades 2 t, with cutting-arm .9, ring 0, ring blade I, rotating knives h, and handle a, substantially as herein shown and described.

3. A gimp cutting and clipping apparatus constructed with a cutting-blade, s, and with forth.
